As someone in Law Enforcement, they'd be arrested. First they assaulted someone and had legit fingerprints EVERYWHERE. It was cruel and unusual punishment to watch.

That escalated quickly! It's a cautionary tale about allowing scantily clad women (who lie about their age,) into your house if you're a husband and father. That was his first and fatal mistake. Too bad that the wife and kids had such a mess to come home to...literally.

A rather crazy film that simply aims to be unpleasant. It actually succeeds, but it's not the kind of horror I like. This is basically an S&M film with a lot of sexual content and not a classic horror film as one might expect. The plot seems to be less important and was not very convincing. At least Keanu Reeves is in it.

Absolutely disgusting movie.

This is the worst movie I’ve seen in my life.

This is the worst movie in the history of thrillers, even p**n in some cases

worst movie i've ever watched in my whole life, trust if i could give this zero stars i absolutely would. Kinda Pregnant was better than this. genuine shite

I saw it late one morning 9 years ago and that's how I fell in love with these two beautiful actresses. But I think the movie is crap.

I definitely WOULD NOT recommend this movie! Rated as horror??! No! should be rated ridiculous! What the crap is all I could think as I watched this! It went from bad to worse to disgustingly stupid. Keanu is a much better actor than that crap he “starred” in. So disappointed. Was this early in his career?!?

It's an awfully stupid movie, but arguably featuring Keanu Reeves' best performance.

The story was poorly written and disappointing.

awful writing awful ending terrible film.

This movie is mess, but this is the type of mess that I like. Ana De Armas is amazing

Why oh why did Mr Reeves agree to this?

HORRÍVEL, TORTURANTE, INFERNO EM FORMA FE FILME. Não recomendo ao meu pior inimigo, me senti torturada a cada segundo do filme. Com certeza esse filme foi feito para ser usado como tortura no inferno.

Please don't watch this movie. Trust me, you're better off never having seen it. It's 90 minutes long, you can watch a great Disney or DreamWorks movie in that time. I am serious, you'll waste your time watching this movie. It really is that bad.

i actually enjoyed knock knock it was a good story a good cast keanu reeves did a great job at acting the girls did a great job at acting as well very suspenseful movie and really good movie.

Watching a pile of fresh dog crap dry is more entertaining than this. Bless Keanu but I stand by it.

Il faut que Keanu Reeves ait besoin d'argent pour accepter de jouer dans ce film. De plus, la finale est insignifiante.

I'm surprised Keanu and Ana agreed to this. They were great in this contrived and annoying story. It's considered a crime/thriller but it's more like satirical comedy.
